Serum Beryllium (Be)
Light alkaline earth metal that acts as a potent hapten, triggering a specific class II MHC-restricted CD4+ T-cell cell-mediated immune response.
Standard vs. Optimal Reference Rangesug/L
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<0.5 ug/L
General reference distribution across unselected commercial populations.
<0.1 ug/L
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Binds human leukocyte antigen HLA-DPB1 with glutamate at position 69, presenting non-self peptides to drive non-caseating granuloma formation.
Differential Diagnosis
Elevated Levels (Be High)
- •Occupational exposure (aerospace, defense, beryllium-copper alloys, dental technology)
Low Levels (Be Low)
- •Absence of beryllium sensitization
- •Normal pulmonary alveolar architecture

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for Be
- Targeted organ system imaging or functional dynamic testing related to granulomatous lung disease
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
